Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a called party guiding method and apparatus for automatically sending a voice message or a video message such as a name of a called party to a calling party. The called party information automatically notifies the calling party of called party information such as the name of the called party. Does the calling party make a call to the intended called party based on this called party information? You can judge whether or not,
It is possible to prevent wrong calls.

[0002]

2. Description of the Related Art As a called party guide in a conventional example, for example, when an incoming call is made to a subscriber registered in advance in an exchange, a guidance message such as the name of the subscriber is sent from the exchange to the calling party. The calling party determines from the guidance message whether or not the intended callee has been called, and when he / she notices that the call is on the wrong line and goes on-hook, the exchange performs processing without calling the called party. If the caller remains off-hook for a certain period of time after the termination or guidance message is sent to the caller, the exchange makes a call to the called party and A method for forming a communication path with a calling party is known (Japanese Patent Laid-Open No. 58-1).
See Japanese Patent No. 65467, "Intercept service system").

Further, when an incoming call is made to a specific subscriber, the calling party accommodation exchange notifies the calling party of the called number or the name of the called party by voice, and after a lapse of a certain time,
An exchange that forms a communication path is known (Japanese Patent Laid-Open No. 61-61).
80938 gazette "telephone exchange").

Further, a voice editing control device is provided in the wireless telephone exchange so that, when an incoming call is made to the mobile device, the voice editing control device sends the name of the called party to the calling party by a voice message instead of the ring back tone. Is known (Japanese Patent Laid-Open No. 61-245662, "Wireless Telephone Switch").
reference).

[0005]

In the called party guidance of the conventional example, the telephone number or name of the called party is notified to the calling party by means of a guidance message, which is desired by the called party. The guidance message could not be sent. Further, the guidance message is transmitted at a predetermined timing either before or during a predetermined call, and it is not possible to select either of them.

Further, in the case of a configuration in which the called party information is sent from the exchange accommodating the calling party to the calling party,
It is necessary to provide a telephone directory file containing all the called party information, read the called party information corresponding to the calling information, and send it as a guide message to the calling party. However, there is a problem that the call processing load increases as the number of calls increases.

Further, in the conventional example in which the called party information is transmitted instead of the ringback tone, it is necessary to include a message that the called party is ringing in the guidance message.
In addition, since the guide message is sent to the calling party while the called party is ringing, the called party may answer off-hook before the calling party notices the wrong call. Even if it is a telephone call, the called party must answer and the exchange side must once establish a communication path, resulting in unnecessary processing.

The telephone of the called party is provided with a function for transmitting the called party information so that the called party information such as the name and telephone number of the called party can be sent before the called party answers the call signal off-hook. Although it is possible to send it out, the configuration of the telephone becomes complicated, and even in the exchange, it is necessary to send out a control signal for sending the called party information during or before sending the ringing signal. It is difficult. Also in the communication network, multimedia including videophones has been promoted, and no countermeasures against erroneous dialing for subscribers equipped with an image terminal device have been taken. INDUSTRIAL APPLICABILITY The present invention allows a subscriber to arbitrarily register the content and transmission timing of a guidance message by voice and image, provides flexibility of guidance of a called party to a calling party, and avoids unnecessary response operation due to erroneous dialing. The purpose is to enable.

FIG. 2 is an explanatory diagram of the registration table according to the embodiment of the present invention. The message number registration table 15 uses the device number (telephone number) of the subscriber as an address for the image message number and the voice message number, respectively. A transmission flag * 1 indicating the presence or absence of transmission is registered. The transmission flag * 1 is "0" indicating no transmission, and "1" indicating transmission.

Message transmission pattern registration table 1
Reference numeral 6 represents a message transmission pattern with the device number of the subscriber as an address, and is represented by "0" indicating that the message is transmitted before transmitting the ringing signal, and "1" indicating that the message is transmitted during the ringing signal transmission. You can register.

The ringback tone transmission presence / absence registration table 17 indicates whether or not the ringback tone is transmitted with the device number of the subscriber as an address, "0" indicates no transmission, "1".
With, it is possible to register the presence of transmission.

FIG. 3 is a flow chart of registration setting according to the embodiment of the present invention. The subscriber receives a special number indicating message registration from any terminal device and subscriber information (subscriber device number / subscriber device number /
Identification information of the subscriber terminal device targeted for service implementation such as a telephone number), message type information (voice or image), ringback tone synthesis registration / non-registration information (whether or not to synthesize and register at message registration), and voice message Alternatively, the image message is transmitted.

The subscriber receives the registration information using the special number from any terminal device, and the exchange judges the message type of the voice message or the image message based on the message type information (A1), and registers the voice message. In the case of,
Whether or not to synthesize and register the ringback tone is determined by the ringback tone synthesis registration presence / absence information (A2),
When not synthesizing, the voice message is registered in the image / voice message device 3 (see FIG. 1) (A5).

When the ringback tone synthesis registration presence / absence information indicates that synthesis registration is present, the voice message and the ringback tone are synthesized and registered (A3). In this case, the ringback tone from the tone generating device 6 and the voice message from the subscriber terminal device are synthesized by the voice synthesizing device 5 and registered in the image / voice message device 3. Then, the “ringback tone transmission presence / absence registration table” is set to “none” (A4). That is, "0" is set in the ringback tone transmission presence / absence registration table 17 shown in FIG. In this case, since the ringback tone to the calling party is included in the voice message, it is possible to eliminate the ringback tone transmission from the tone generation device 6 when the call arrives.

Then, the voice message number is registered in the "message number registration table" (A6). That is, a voice message is registered in the image / voice message device 3 (see FIG. 1), and the voice message number of the registration number is changed to that shown in FIG.
The message number registration table 15 shown in FIG.

When the image message is to be registered, it is determined in step (A7) similar to step (A2) whether or not the ring back tone is to be combined and registered. The image message is registered in the image / voice message device 3 (A10). In this case, the voice message can be registered together with the image message.

When the ring back tone is combined and registered, the image message including voice and the ring back tone are combined and registered in the image / voice message device 3 (A
8), "none" is registered in the "ringback tone transmission presence / absence registration table" (A9). That is, since the image / voice message and the ring back tone are combined and stored in the image / voice message device 3, it is not necessary to send the ring back tone from the tone generation device 6 when receiving a call. In this case, "0" indicating no transmission is automatically set in the ringback tone transmission presence / absence registration table 17. Then, the image message number corresponding to the registration number of the image / voice message device 3 is registered in the "message number registration table" (A11).

FIG. 4 is a flowchart for confirming a message according to the embodiment of the present invention. The subscriber confirms a special number for confirming a message from any terminal device, subscriber information such as subscriber device number and telephone number, and voice message. And message type information indicating whether it is an image message or not. The exchange determines the message type (B1), and reads the voice message number from the message number registration table 15 shown in FIG. 2 based on the subscriber information in response to the identification of the voice message or the image message (B2). Alternatively, the image message number is read (B7).

Next, the information on the presence / absence of ringback tone transmission is read from the ringback tone transmission presence / absence registration table 17 shown in FIG. 2 (B3), (B8), and it is determined whether or not ringback tone transmission is present (B4). , (B9), if the ringback tone is transmitted, the voice message or the image message containing the voice and the ringback tone are combined and transmitted (B5), (B10). If the ringback tone is not transmitted, , A voice message or an image message including voice is sent (B6), (B11). The subscriber can confirm the registered message contents by the voice message, the image message including the voice, or the message combined with the ring back tone.

FIG. 5 is a flowchart of message transmission pattern registration according to the embodiment of the present invention. The subscriber sends a special number for message transmission pattern registration, subscriber information, and pre-call transmission from any terminal device to the exchange. Or a message transmission pattern indicating that the message is transmitted during a call. The exchange identifies the message transmission pattern (C1), sets pre-call transmission by "0" in the "message transmission pattern registration table" in the case of pre-call transmission (C2), and in the case of mid-call transmission. , "Calling message sending pattern setting table" is set to "1" during sending call (C
3).

FIG. 6 is a flow chart for registering the presence / absence of ringback tone transmission according to the embodiment of the present invention. The subscriber registers a special number for registering the presence / absence of ringback tone transmission from any terminal device, subscriber information, and ringback tone. Information on the presence / absence of transmission (whether or not to synthesize at the time of message transmission) is transmitted. The exchange identifies the presence / absence of ringback tone transmission (D1), and if transmission is present, sets "1" for transmission presence in the "ringback tone transmission presence / absence registration table" (D2). Sets "0" for no transmission in the "ringback tone transmission presence / absence registration table" (D3).

FIG. 7 is a flowchart for registering the presence / absence of message transmission according to the embodiment of the present invention. Even if a voice message or an image message is registered, it can be registered so as to stop the message transmission. Is a special number for registering the presence or absence of message transmission from any terminal device,
The subscriber information, the message type information, and the message transmission / non-transmission information are transmitted. The exchange discriminates whether the message type is voice or image (E1), judges the presence or absence of message transmission in the case of voice message or image message (E2), (E5), and in the case of message transmission,
"1" is set in the "message number registration table" to indicate whether a voice message is transmitted or an image message is transmitted (E3), (E6). If no message is sent, "0" is set in the "message number registration table" indicating that no voice message is sent or no image message is sent (E4) and (E7).

By the above-mentioned operation, the voice message or the image message including the voice is registered in the image / voice message device 3, and the message number registration table 15, the message transmission pattern registration table 16 and the ring back tone transmission presence / absence registration table 17 are registered. Data part 1 including and
2, the registered contents of the image / voice message device 3 can be managed.

FIG. 8, FIG. 9 and FIG. 10 are flow charts at the time of sending a message according to the embodiment of the present invention. For example, when the telephone number of the subscriber terminal device A is dialed from the subscriber terminal device B in FIG. , The central control unit 1 of the exchange,
The subscriber A is identified by the calling telephone number analysis, and the storage device 3
The data section 12 is searched according to the control program by the terminal control section 13 of the program section 11 of FIG. * 1 is read, and a message sending pattern indicating whether the message is sent before sending the calling signal or is sent while the calling signal is being sent from the message sending pattern registration table 16, and whether or not the ring back tone is sent is registered. The ringback tone transmission presence / absence information is read from the table 17.

As described above, the registered contents are read from the message transmission pattern registration table 16 and it is judged whether or not the message transmission pattern is pre-call transmission (F1). If it is not pre-call transmission, that is, as a message transmission pattern. When "1" is set and registered, the calling of the called party is started (F2). That is, a call signal is sent from the exchange to the subscriber terminal device A by a well-known configuration (not shown).

Then, regardless of whether or not the message sending pattern is before calling, the caller telephone type is identified (F3). This calling party telephone type can be easily identified on the basis of the called party information such as the telephone number of the called party and the calling party information in ISDN. In a network system that does not transfer caller information, the above-mentioned identification can be determined as a videophone and the processing can proceed.

When the caller telephone type is a video telephone,
It is determined whether or not the image message is transmitted (F4). If the image message is transmitted, the image message is transmitted to the calling party (F).
5). That is, the message number registration table 15 is searched based on the called party information, and the image message number and the sending flag *
1 and the image message number is stored, the image message is registered. Therefore, the image message is read from the image / voice message device 3 based on the image message number, and the calling party joins. Person terminal device B
To send to. In FIG. 1, the image message is sent to the subscriber terminal device B of the calling party via the path of the network device 2.

When the caller telephone type is a general telephone,
Alternatively, if there is no image message transmission or after the image message transmission is started, it is determined whether or not there is a voice message transmission (F6). If no voice message is sent,
It is determined whether or not the image message is transmitted (F7). If the image message is not transmitted, the processing is shifted to the normal calling (F7).
8) Then, the message sending process ends.

If the voice message is transmitted, it is determined whether or not the ring back tone is transmitted (F9). If the ring back tone is transmitted, the voice message and the ring back tone are combined and transmitted to the caller. (F10),
If no ringback tone is sent, a voice message is sent to the calling party (F11). For example, the ringback tone from the tone generation device 6 and the image / voice message device 4 via the path of the network device 2
The voice message read from is synthesized by the voice synthesizing device 5 and sent to the subscriber terminal device B of the calling party via the path.

Then, it is judged whether the called party is calling (F
12) If it is not ringing, it is judged whether or not there is a call request by the caller (F13). If there is no call request, it is judged whether or not the caller is abandoning midway (F14).
It is determined whether or not the message transmission is completed (F1
5) If not completed, move to step (F13),
When finished, shifts to the normal calling state (F1
6).

If there is a call request from the calling party in step (F13), the system shifts to a normal calling state (F1).
7). Further, in step (F14), when the caller abandons on the way, the state shifts to an empty state (F18).

In step (F12), if the called party is calling, it is determined whether or not the called party is the answer (F19). If the called party is the answer, the call is transferred (F23). . That is, the central control unit 1 of the exchange controls the network unit 2 to form a path, and a call is made between the subscribers A and B.

When the called party does not respond, it is determined whether the caller is abandoning midway (F20). When the callee is not abandoning midway, it is determined whether the message is finished (F21). Start sending messages again (F2
2). That is, the registered message is repeatedly sent to the calling party until the called party answers.

In step (F20), if the caller abandoned midway, the state shifts to an empty state (F24). That is, the exchange returns to the initial state for the subscriber B, as in the case of the caller abandonment in step (F14).

When the image / voice message is registered in the image / voice message device 4 from the subscriber terminal device A, the path of the network device 2 is formed, and the subscriber terminal device A
The image message or the voice message inputted from is stored in the image / voice message device 4, and the setting registration of the message sending pattern can be performed. When confirming the registered contents, a path of or is formed, and the registered image / voice message or the image / voice message synthesized with the ringback tone by the voice synthesizer 5 is registered in the subscriber terminal device A. You can check.

When a call is made from the subscriber terminal device B to the subscriber terminal device A when the image / voice message is not registered, the call is sent from the call signal transmitting mechanism (not shown) to the subscriber terminal device A. A signal is transmitted and the subscriber terminal device B
, A path is formed for the tone generator 6
The ringback tone from is sent.

Further, when the image / voice message is registered from the subscriber terminal device A and the message transmission pattern is set and registered before the transmission of the calling signal, when the subscriber terminal device B makes a call to this subscriber terminal device A, The switchboard sends the image / voice message read from the image / voice message device 4 to the subscriber terminal device B via the path of the network device 2 before sending the call signal to the subscriber terminal device A. If the subscriber terminal device B performs hooking or key input operation on the telephone while receiving the image / voice message, the exchange stops sending the image / voice message from the image / voice message device 4. Moreover, it is possible to start sending a calling signal to the subscriber's terminal device A of the called party.

Further, when the image / voice message is registered from the subscriber terminal device A and the message transmission pattern is set and registered during transmission of the calling signal, when the subscriber terminal device B makes a call to this subscriber terminal device A, The exchange sends a calling signal to the subscriber terminal device A and sends the image / voice message read from the image / voice message device 4 through the path of the network device 2 to the subscriber terminal device B of the calling party. Send to. When the called subscriber's subscriber terminal device A immediately responds to the ringing signal during the sending of the image / voice message, it is possible that the calling party confirms the called party by the image / voice message. Also, the transmission of the image / voice message can be stopped, the path of the network device 2 can be formed, and the communication state can be entered.

When a subscriber accommodated in an exchange that does not have a caller information transfer function makes a call when sending an image / voice message, step (F3) in FIG.
In this case, since the caller telephone type cannot be identified, it is regarded as a video telephone and the registered image message is also transmitted. If it is a video telephone, the image message can be displayed, and if it is a general telephone, You will only be able to receive voice messages.

As shown in FIG. 1 as another network device 7, even when a subscriber accommodated in another exchange makes a call to, for example, the subscriber terminal device A, the image from the subscriber terminal device A is displayed. / The image / voice message registered in the voice message device 4 can be transmitted according to the message transmission pattern set and registered. Further, although the image / voice message device 4 is installed in a central station or the like and the processing becomes complicated, it is possible to perform centralized management.

[0053]

As described above, according to the present invention, the image message and the voice message to be sent to the calling party are arbitrarily registered, changed and confirmed by the called subscriber in the image / voice message apparatus 4. The subscriber can set and register the message sending pattern instructing the sending of the image / voice message before or during sending the calling signal to the called party. Various messages can be sent to the calling party according to the request of the caller.

Therefore, the calling party can notice the wrong telephone call before the called party answers, and the called party can be advertised by the image / voice message. Also, since the called party can send the image / voice message until the response, the possibility of avoiding the caller's abandonment can be increased.

Image / voice message device 4 and image / voice message device 4
Each registration table 15-1 for managing voice messages, etc.
With 7, it is possible to send the image / voice message registered by the subscriber to the calling party as described above.
